“…Population density in the coastal zones of South Asia has increased drastically during the last 15 years, and this has led to a further increase in risk due to natural hazards (Mani Murali et al 2013). To date, the coastal hazard assessments were carried out at Puducherry and Cuddalore in South India (Mani Murali et al 2013;Saxena et al 2013), western Bangladesh (Karim and Mimura 2008) and the Indus Delta in Pakistan (Salik et al 2015). In this study, mapping of this hazard along the South Asian coast was carried out by integrating the following six different parameters: …”

170 Research ReportsThe publications in this series cover a wide range of subjects-from computer modeling to experience with water user associations-and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to provide evidence-based solutions to sustainably manage water and land resources for food security, people's livelihoods and the environment. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a tangible impact on poverty reduction, food security and ecosystem health.

“…Similar efforts in developing hazard and risk information in Sri Lanka were supported by the United Nations Development Programme (UNDP) (MoDM 2005). In India and Pakistan, most relevant studies have been confined to state/district level (Abid et al 2016;Deen 2015;Kunte et al 2014;Guleria and Patterson Edward 2012;Rafiq and Blaschke 2012;Saxena et al 2013).…”

“…The tropical cyclone-induced storm surge hazard is defined by the probability of damaging situations in a given area within a specified time period (Saxena et al 2013). The storm surge flooding depths under different return intervals are the most prevalent indicators for this hazard assessment (Shepard et al 2012;Li and Li 2013).…”

“…These hydro-meteorological natural phenomena generally form over tropical oceans, and are referred to as cyclones, typhoons and hurricanes based on their particular locations (Puotinen 2007;Bobby 2012). The destructive characteristics, for example, sustained high winds, intensive rainfall, high storm surges and coastal inundations, are typically associated with land-falling tropical cyclones (Saxena et al 2013;Xu et al 2015).…”

“…Several recent studies predicted that the intensity of tropical cyclones will likely increase in the coming decades under most climate change scenarios (Mendelsohn et al 2012;Yin et al 2013;Krishnamohan et al 2014;Deo and Ganer 2014;Fang et al 2016). In particular, storm surge generated from tropical cyclones may be exacerbated when coupled with climate change-induced sea level rise (Frazier et al 2010;Saxena et al 2013;Fang et al 2016).…”

Tropical cyclones are one of the most catastrophic natural hazards regularly affecting tropical coastal areas globally. The overall impacts of tropical cyclones can be minimized using a range of management approaches, in terms of: prevention/reduction, and preparedness. Accurate and detailed spatial information on the natural and built environment is required to support the development, implementation and evaluation of these cyclone management approaches. There is a lack of appropriate mapping approaches and spatial models at local scales (<1000 km 2 ) to derive this information.This thesis developed and evaluated mapping approaches and spatial models at the local scale (<1000 km 2 ) by integrating remote sensing, field data and spatial analysis for assessing, monitoring and managing tropical cyclone impacts. Three specific objectives were addressed: (1) developing and evaluating an approach for assessing the multiple impacts of tropical cyclones through objectbased image analysis applied to moderate spatial resolution satellite imagery; (2) developing and testing a risk mapping approach for tropical cyclone impacts using an analytical hierarchy process (AHP) with data derived from remote sensing, field data and spatial analysis; and (3) producing and evaluating a simple risk modelling approach under present and future climate scenarios for tropical cyclone impacts using remote sensing, field data and spatial analysis. The developed mapping approaches and models were tested to justify the applicability in Sarankhola Upazila (151 km 2 ), a local government area in coastal Bangladesh. Cyclone Sidr (2007) was used as a case study for objective one in the study site.After introductory, review and research approach chapters, chapter four developed a method for mapping the multiple impacts of tropical cyclones. The object-based approach was used to map land cover types in pre-and post-cyclone Sidr (2007) damage to cropland and the changes to landforms. The damage results were verified using local damage reports and high spatial resolution satellite imagery that were taken after the cyclone.ii Chapter five integrated remote sensing, field data and spatial analysis for developing a multi-criteria tropical cyclone risk mapping approach at a local scale. Three risk components: 1-vulnerability and exposure; 2-hazard; and 3-mitigation capacity, and their 14 relevant criteria were considered.Thematic raster map layers were prepared for every criterion and weighted using AHP. A weighted overlay technique was used for generating vulnerability, hazard, mitigation capacity and risk maps.The verified results revealed that detailed cyclone risk information can be successfully mapped using geospatial techniques and an AHP at the local scale. The study found that incorporation of mitigation capacity significantly influenced the risk results. The approach also solved several issues for local level multi-criteria data generation, processing and integration. The approach provided was validated by confidence level assessment an...
